Cushing’s syndrome is an excess production of cortisol, the body’s primary intrinsic steroid. This can result in a host of problems. Prolong exposure to cortisol can result in weight gain, acne, thinning hair, and easy bruising. Patients can even suffer from diabetes, increased susceptibility to infection, and brittle bones. Over production of cortisol can be associated with both benign and malignant conditions of the adrenal gland.
